LAMP.

Specification of Letters Patent.

Patented June 23, 1914..

To all whom 'it may concern:

Be it known that I, CHARLES E. GODLEY, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Lamp, of which the following is a specification.

This invention relates to lamps intended for use in the open exposed to wind and rain, and its object is to provide a lamp wherein the proper ventilation shall be secured and the effect of sudden gusts of air overcome; and to provide a construction in which the parts may be easily assembled, and so sei curely clamped together that rattling shall be overcome.

This invention consists in the details of construction shown, described and particularly pointed out in the claims.

In the drawings, Figure 1, is a side elevation of a lam in which this invention may be embodie Fig. 2 is a vertical section through the upper portion or head of Fig. 1. Fig. 3 is a section on the line 3-l3 of Fig. 2. Fig. 4 is a sectionon the line 4 4 of Fig. 2.' Fig. 5 is a side elevation of the cap. Fig. 6 is a side elevation of the chimney tube and perforated curtain.

Similar reference characters refer to like parts throughout the several views.

My improved construction is shown as embodied in a lamp comprising a font 1, a body 2, havin a closed rear end 3 and a Haring front end 4, which may be closed by a lens door 5, that supports the lens G in the usual manner. An opening is formed in the upper side of the body to receive a head that comprises a lower section 8, having its lower end turned inwardly to form an annular bearing shoulder; 9 Whose inner edge may be turneddownwardly to forni the cylindrical extension 10 that passes through the opening in the body and centers the head in respect thereto. The lower section of the head is also provided with a series of draft openings 11, and has a flaring upper end 1Q, the edge of which may be turned inwardly to form a bead 13 that may be -received by the similarly beaded lower end 15 of the upper section 16 of the head. The upper portion of the section 16 'may be constricted to form-an edge 17 from which the top 18, having a small central aperture, may be supported, b a series of-posts 19 `(Flg. 3)

provided wit the channels 20'in their inner l surfaces, the posts being spaced apart somewhat to form a series of passages21, fonthe burnt gases and hot air. A handle 22 may be attached to the head in any desired 'manner.

Passing longitudinally through the opening in the top of the body is a chimney tube having a cylindrical body portion 25 and a Haring lower end 26, whose outer edge is turned upwardly at 27 to receive and support a curtain 28 which, as show`n,`is of the shape ofthe frustum of a cone, and vwhich may have at its upper end the inturned an- `nular ange 29 that bears upon the body 2.

The curtain preferably provided with a series of small perfOratiOnsBO. "The chimney tube is spaced somewhat from the cylindrical extension 10 to form an annular passage through which air entering the openings 11 may pass downwardly into the space inclosed by the curtain 28, and through the perforations 3() into the body of the lanip. The upper portion of the chimney tube tits rather snugly Within the edge, 17 of the head, and is provided with a series of peripheral openings 33 that may be formed by striking from the body of the tube the inwardly inclined tongues Set, and by removinfr portions of the tube above these tongues. ther portions of the tube mav be bent inwardly as indicated at 35 to form reinforcing members. The upper end of the chimney tube may extend above the edge 17 and have a closed end 37 that is supported from the body of the tube by a series et posts 38 having ribs 3Q thereon corresponc.- ing to and are received by the channels Q0 in the posts 19 of the head, whereby rel ative angular movement of the chimney tube and the head is prevented. Between 'the posts 38 are a series of openings 36, corre spending to the openings between the posts 19. These openings are preferably toi-ined by bending the reinforcing flanges ,40 inn wardly. The end 37 preferably has a central aperture corresponding to the aperture in the cover 18 of the. head, and may have soldered or otherwise, vsecured to its lower surface a threaded nut 41.

Fitting upon the upper surface ot'.A the head 1S is a cap that may be formed of aY lower section 43 having a beaded edge @i that is received by the beaded edge 4.5 of an upper section 46. The lowersecticn of the cap may be perforated in alinement With'tzhe perforations in the parts 37 and 18, and through these perforations the threadedbolt 47 may pass, said bolt preferably having a head 48 that may be soldered to the lower section of the cap.

The parts are assembled by opening the lens door and inserting the chimney tube and curtain from below. The head is then positioned from above, after which the bolt 47 is inserted and the posts rigidly secured together by turning the cap to screw the l,bolt 47 into the nut 4l. While the chimneyetube, cap and curtain areshown applied to a substantially globular lamp body havinga Haring front, it is clearn that these improvements may be applied to lamp bodies of widely different forms.. Y

V`Part of the air entering through the openings 11 passes downwardly into the space between the curtain and the chim'neytube and part of it passes upwardly into the space between the tube and the head. The downward current is intercepted by the'curtain through the small perforations of which it passes rather slowly and regularly by which the effect of sudden drafts is largely overcome. The air is then received in the body of the lamp, from which it passes upwardly into the chimney tube and outthrough the openings between the posts 38. The upward current of air in the head passes into the chimney tube through the openings 33 and on.

wardly through the open-ings 36 with the air coming up through the tube, the tongues 34 serving to direct the air in its course and to prevent back draft down the chimney tube.

It is obvious that many changes may be made in the details of my construction witholut departing from the spirit of my inven- `tron. I do not therefore, wish to be limited otherwise than as indicated by the subjoined claims.
